摘　　要：目的引导骨再生(guided bone regeneration,GBR)技术是解决种植体周围骨损伤缺的有效方法,文中通过临床回顾性研究,评价GBR术同期牙种植对美学区种植体周软组织的影响。方法选取45名患者共60颗(其中基于GBR后种植30颗,常规种植30颗)负重1年的种植体进行临床病历回顾,在术后的3个时间点(种植体暴露口腔后1个月为T1,完成永久修复体之后为T2,以及功能负荷1年后为T3,分别记录了各组种植体的牙周探诊深度和龈乳头指数,分析行GBR术对前牙种植的牙周指数有无影响。结果对比3个时间点2组临床资料牙周探诊指数的变化,GBR组:T1(2.11±0.68)mm,T2(2.13±0.70)mm,T3(2.31±0.84)mm;常规种植组:T1(2.08±0.71)mm,T2(2.15±0.70)mm,T3(2.27±0.84)mm,2组间差异无统计学意义(P>0.05)。龈乳头指数的2组频数分布差异也无统计学意义(P>0.05)。结论 GBR术对美学区牙种植体周牙龈未发现明显影响。Objective The technology of guided bone regeneration is an effective treatment for the injure in aesthetic zones.The aim of this study is to evaluate the effect of guided bone regeneration（GBR） on prei-implant soft tissues in aesthetic zones.Methods We chose 60 implants done in our department up to 1 year after functional loading,with 30 of GBR and the other 30 of regular implant.Pocket probing depth and papilla index were assessed during a 1-year follow up,which was done at 3 points： a month after the exposure of implant（T1）,after the placement of fixed crown（T2） and 1 year after functional loading（T3）.The data were collected to analyze the effect of GBR on peri-implant soft tissues.Results The pocket probing depths of GBR group were： T1（2.11±0.68） mm,T2（2.13±0.70） mm,T3（2.31±0.84） mm and those of regular group were： T1（2.08±0.71） mm,T2（2.15±0.70） mm,T3（2.27±0.84） mm,respectively.There was no significant statistic difference between the two groups（P0.05）.The frequency distributions of the scores of papilla index for both groups were also similar to each other.Conclusion We did not found GBR surgery with any effect on peri-implant soft tissues in aesthetic dental implantation.
